Own-brand products account for a large share of grocery sales, and where they come from explains a great deal about their pricing.
Contract manufacturing
Products made by third parties to a retailer's specification.
Which is the standard arrangement across most categories.
Some manufacturers produce both branded and own-label goods in the same facility.
Same factory, different product
The common claim that own brands are identical to branded equivalents.
Which is sometimes true and frequently not.
Specifications differ in ingredients, proportions and processing even where the facility is shared.
Tiering
Value, standard and premium ranges under retailer labels.
Which target different price points with genuinely different specifications.
The value tier is generally a materially different product rather than the same one packaged cheaply.
Why they cost less
No advertising spend, no brand investment and guaranteed volume for the manufacturer.
Which removes real costs rather than reflecting lower quality.
Marketing is a substantial proportion of a branded product's cost in many categories.
Blind testing
Consumer organisations conduct comparative tasting and testing regularly.
Which frequently finds own brands performing comparably or better.
Results vary substantially by category, and published findings are freely available.
Ingredient labels
Listed in descending order by weight, which allows direct comparison.
Which is more informative than any packaging claim.
Comparing the label of a branded and an own-brand product takes seconds and settles the question for that item.
Packaging and perception
Premium own-label packaging deliberately signals quality.
Which affects perception measurably in blind versus sighted testing.
Discount retailers
Operate almost entirely on own label, which is central to their cost structure.
Comparative basket studies show consistent differences and are published regularly.
Supplier relationships
Own-label contracts provide volume certainty and thin margins for manufacturers.
Which makes the relationship valuable and vulnerable.
Supplier codes of practice regulate aspects of this in several jurisdictions.
Copycat packaging
Own-label designs resembling branded equivalents.
Which has produced litigation and regulatory attention.
The similarity is deliberate and is intended to transfer brand associations.
Quality variation over time
Specifications can change without any packaging change.
Which is why a product can seem different from the one you remember.
Ingredient lists are the reliable way to check.
Premium tiers
Frequently genuinely differentiated with higher-specification ingredients.
Which is where own label competes with branded goods on quality rather than price.
Testing yourself
Buying both once and comparing is definitive for your own preferences.
Which costs the price difference on one purchase and settles the question permanently for that item.
Category variation
Own-label performance relative to brands varies enormously by product type.
Which is why blanket advice about own brands is unhelpful.
Consumer testing results by category are the useful guide.
Manufacturer identification
Packaging sometimes carries identification codes indicating the producing facility.
Which occasionally reveals shared production with branded goods.
This is not a reliable general method and is interesting where it applies.
Innovation
Branded manufacturers invest in product development that own labels frequently follow.
Which is part of what the brand premium funds.
New formats and formulations generally appear under brands first.
Price gap trends
The gap between branded and own-label pricing has varied with inflation and competitive pressure.
Which is tracked by market research firms and reported publicly.
The practical approach
Try own-label in categories where you buy regularly and compare directly. One purchase settles it.
The general finding
Own label is frequently comparable and occasionally better, varying enormously by category.
Which means the only reliable answer is to try the ones you buy regularly.
The saving at household scale
Switching in a handful of frequently bought categories produces a measurable annual difference.
Which is a larger effect than most promotional savings.
A closing note
The claim that own label is identical to branded goods is too strong, and so is the assumption that it is worse. Both are category-specific questions with a cheap and definitive test available: buy both once and compare.
Allergen and dietary information
Labelling requirements apply identically to own label and branded goods.
Which means the information is equally reliable.
Formulation changes are a specific risk for anyone managing an allergy, and rechecking labels periodically is advised.
Organic and certification claims
Certification schemes apply to own label as to brands.
Which makes certified own-label products a genuine option at lower cost.
Certification marks are verifiable through the scheme operators.
Availability
Own-label ranges are exclusive to each retailer.
Which means a preferred product ties you to that shop.
The short version
Contract-manufactured to retailer specification, cheaper because of what is removed rather than what is compromised, and variable by category.
Which makes direct comparison the only reliable method.
Where to read more
Consumer organisations publish blind taste and performance testing across grocery categories annually.
Which answers the question category by category rather than in general.
The results are frequently surprising in both directions, which is why they are worth reading rather than assuming.
